Bidirectional imputation of spatial GPS trajectories with missingness using sparse online Gaussian Process
OBJECTIVE: We propose a bidirectional GPS imputation method that can recover real-world mobility trajectories even when a substantial proportion of the data are missing. The time complexity of our online method is linear in the sample size, and it provides accurate estimates on daily or hourly summa...
